Triple Offset Butterfly Valve

triple offset butterfly valves

The triple offset butterfly valve is a special type of quarter-turn valve that is often used in demanding industrial applications. This unique design offers several advantages over other types of valves and can handle a variety of fluids, including highly corrosive and abrasive materials. It is also able to cope with high temperatures and pressures, making it an ideal choice for steam service and process control systems.

A triple offset butterfly valve is designed to eliminate the rubbing between the seat and seal ring that can occur when the valve opens or closes. This reduces seat and seal wear and extends the cycle life of the valve. Triple-offset valves are available in a wide range of sizes and can be configured to suit a number of different application requirements.

Maintenance and Troubleshooting Tips for Triple Offset Butterfly Valves

Triple-offset valves are able to achieve higher sealing pressures than other types of butterfly valve. This is thanks to their oblique sealing disc and three concentric seals. The valve is also better able to tolerate dirt and can function effectively in dirty or abrasive fluids, allowing it to operate more efficiently than conventional valves.

Triple-offset valves can also be fitted with corrosion-resistant alloys for the seat and disc to deliver a metal-to-metal seal that is ideally suited to harsh conditions. This is a key advantage over other types of butterfly valve that use elastomers or soft materials for the seat, which can deteriorate with increased temperature and are susceptible to corrosion.
